 *                   Style sheet for the W3C specifications                   *
 *
 * Special classes handled by this style sheet include:
 *
 * Indices
 *   - .toc for the Table of Contents (<ol class="toc">)
 *     + <span class="secno"> for the section numbers
 *   - #toc for the Table of Contents (<nav id="toc">)
 *   - ul.index for Indices (<a href="#ref">term</a><span>, in §N.M</span>)
 *   - table.index for Index Tables (e.g. for properties or elements)
 *
 * Structural Markup
 *   - table.data for general data tables
 *     -> use 'scope' attribute, <colgroup>, <thead>, and <tbody> for best results !
 *     -> use <table class='complex data'> for extra-complex tables
 *     -> use <td class='long'> for paragraph-length cell content
 *     -> use <td class='pre'> when manual line breaks/indentation would help readability
 *   - dl.switch for switch statements
 *   - ol.algorithm for algorithms (helps to visualize nesting)
 *   - .figure and .caption (HTML4) and figure and figcaption (HTML5)
 *     -> .sidefigure for right-floated figures
 *   - ins/del
 *
 * Code
 *   - pre and code
 *
 * Special Sections
 *   - .note       for informative notes             (div, p, span, aside, details)
 *   - .example    for informative examples          (div, p, pre, span)
 *   - .issue      for issues                        (div, p, span)
 *   - .assertion  for assertions                    (div, p, span)
 *   - .advisement for loud normative statements     (div, p, strong)
 *   - .annoying-warning for spec obsoletion notices (div, aside, details)
 *
 * Definition Boxes
 *   - pre.def   for WebIDL definitions
 *   - table.def for tables that define other entities (e.g. CSS properties)
 *   - dl.def    for definition lists that define other entitles (e.g. HTML elements)
 *
 * Numbering
 *   - .secno for section numbers in .toc and headings (<span class='secno'>3.2</span>)
 *   - .marker for source-inserted example/figure/issue numbers (<span class='marker'>Issue 4</span>)
 *   - ::before styled for CSS-generated issue/example/figure numbers:
 *     -> Documents wishing to use this only need to add
 *        figcaption::before,
 *        .caption::before { content: "Figure "  counter(figure) " ";  }
 *        .example::before { content: "Example " counter(example) " "; }
 *        .issue::before   { content: "Issue "   counter(issue) " ";   }
 *
 * Header Stuff (ignore, just don't conflict with these classes)
 *   - .head for the header
 *   - .copyright for the copyright
 *
 * Miscellaneous
 *   - .overlarge for things that should be as wide as possible, even if
 *     that overflows the body text area. This can be used on an item or
 *     on its container, depending on the effect desired.
 *     Note that this styling basically doesn't help at all when printing,
 *     since A4 paper isn't much wider than the max-width here.
 *     It's better to design things to fit into a narrower measure if possible.
 *   - js-added ToC jump links (see fixup.js)

   <p>Contact pickers are frequently seen in various desktop and native mobile applications for a variety
of use cases. This specification defines an API to bring contact pickers to the web, which will
enable new use cases for web apps, such as:</p>
   <ul>
    <li data-md>
     <p>Bootstrapping a user’s social graph for social networks.</p>
    <li data-md>
     <p>Selecting the recipients of a message within an e-mail application.</p>
   </ul>
   <p>The contact picker model was chosen to give full control to users over the shared data, allowing
users to choose exactly which contacts to provide to the website. The contact picker model gives
websites one-off access to a user’s contacts, meaning developers have to request access to the
user’s contacts every time they need it. This differs from some native contact APIs, but is
necessary for ensuring users' contacts are not accessed without their knowledge and explicit
consent.</p>

   <p>Exposing contact information has a clear privacy impact, in terms of exposing PII of uninvolved
parties. A picker model is enforced so that the user agent can offer a user experience that makes
it clear what information is going to be shared with the website and when.</p>
   <p>The following constraints are also enforced:</p>
   <ul>
    <li data-md>
     <p>The API is only available in a <a data-link-type="dfn" href="https://html.spec.whatwg.org/multipage/browsers.html#top-level-browsing-context" id="ref-for-top-level-browsing-context">top-level browsing context</a> which must also be a <a data-link-type="dfn" href="https://w3c.github.io/webappsec-secure-contexts/#secure-contexts" id="ref-for-secure-contexts">secure context</a>. These restrictions help ensure that the provided contact information reaches
its intended recipient.</p>
    <li data-md>
     <p>A user gesture is needed to initiate the API, to disallow programmatic requests to the user’s
contacts.</p>
